I wonder, does Intel's TSX/HLE help with these workloads? If it's read-only then I'd expect that it'd be able to elide a lot of the locking (assuming the Intel-designed heuristics do the job).
- anarazel 10y agoI'd bought one of the first haswell notebooks to play around with tsx. Before I'd time to do so Intel found the tsx bug... I hope to have time to play around with it one I have new hardware (I refuse to do performance development on virtual). But honestly, most remaining performance/scalability problems in pg are more algorithmically caused. So micro optimization, and that's what I'd call tax/hle, aren't likely to biggest bottleneck.
- ziedaniel1 10y agoWasn't TSX only enabled on Xeons to begin with?
- anarazel 10y agoNo, the higher end i7 mobile processors had it as well (i7 48xxhq or something IIRC).
- creshal 10y agoI could've sworn that Intel actually demonstrated TSX on a Postgres fork they created, but my Google-fu is too weak to find the slides again.
